I haven't seen another thread covering this, so hopefully someone finds it useful. I bought this Joseph Rodgers a while back, gave it a clean and then hit the stones. This was the result.

Having only the hand tools I usually use for restores, I put it in the too-hard bin. Then a couple of days ago I was bored, so I dug it out and had a go at it with the only relevant power tool I own, This straight grinder.

I had a 40mm dia stone that came as part of an accessory package, which I used to tickle it down to this.

Pretty ugly, but after about half an hour or less with 80# it looked like this.

I checked to make sure it was symmetrical by touch and sight and before i started sanding I taped it and gave it a few strokes on the bevel setter to make sure grinding was complete and that the contact was all along the edge. I then sanded it down until I'd removed all the grind marks with 80# before swapping to 400#. Too big a jump, but that's all I had here. After the 400# I put it to the bevel setter again to see what I had.

There are still stria from the 80#, so I'm going to get some 240# to help polish it before the final sharpening, but it looks like its going to hone up alright.
